1 INSTRUCTIONS FOR ASSEMBLY AND OPERATION Flow pressure water heaters type 12H, 15H, 18H, 21H

2 Before using the heater please read the instructions carefully. In the future it will pay off in the form of failure-free operation for a long time. Flow water heaters series 12H, 15H, 18H, 21H with two-degree hydraulic switch are designed for heating utility water. Warm water can provided to a couple of water drawing points located in different rooms. These heaters are equipped with heating spirals that are directly washed by water. This direct heating process prevents limescale from settling and ensures high efficiency and quick heating of water. The electronic system of the heater is equipped with an air block sensor that decreases to minimum the possibility to damage immersion heaters due to air blocking of the water supply installation. It also gives bigger possibilities in the selection of power for different degrees switching on depending on the amount of flowing water. The device cannot be installed in rooms in which temperature may fall below 0 C, as well as in which there is a risk of explosion. This equipment is not designed to be used by persons (including children) of the limited physical, sensory or mental fitness, unless their use is supervised. Attention must be paid to children so that they would not play with the device. Instructions for assembly Installation as well as start-up of the -H heater should be done by an authorized person in accordance with the instructions included in the Instructions. Any installation works should be done with disconnected power and water supply. Electric installation of the heater should be made pursuant to the binding regulations. The device should be permanently connected to an electrical installation with an earth terminal. Electrical installation should be equipped with a residual circuit breaker with the protection against electric shock, as well as a breaker ensuring the disconnecting of the device from the source of power supply in which the distance between contacts should be not less than 3 mm. 1. To the place in which the heater is to be installed, electrical as well as water installation should be supplied using the assembly template for that. 2. Drill holes and insert expansion plug. 3. After supplying cold water, install the control valve with a filter (pict. 3). 4. Unscrew the located at the bottom of the heater casing screw fastening the casing (pict. 1), take off the cover and disconnect the belt cable by taking out the plug from the socked marked KEYBOARD (pict. 2). 5. Screw the heater to the wall with the fastening screws, having previously led the supply cable through the hole. 6. Check the turning on of the pressure switch. 7. Remove blanking plugs from water connections. 8. Connect the heater to water installation (pict. supply connection marked 9, outlet marked 10) 2

Diagram of electrical installation Start-up In order to remove air from the water installation and the heater prior to turning on electric power, open warm water valve for about 20 seconds. Then turn on the power. After turning on the power all indicators will light. Warm water valve should be opened again. The indicators will go out for about 10 seconds. After that time the device will be in standby. Pulsating light on the power indicator will signal the start of the water heating process, as well as the chosen power. Close warm water valve. The heater will turn off heating signalling that state with the change of the pulsating light of the indicator to continuous. By means of or + buttons, the desired power on the power indicator can be set. 4

5 Use Setting the heating power is done by pressing one of the buttons on the casing marked with or + signs. Detecting by the heating system bigger flow than the minimum for I power degree will result in switching it on what is signalled with pulsating red light on the power indicator. The drop of the flow below the switching point will result in the switching the heating off, and the pulsating light will change into continuous. Adjustment of temperature of outlet water may be done by changing the heating power. Heating power 1 low temperature of outlet water with low, economical power consumption. Heating power 5 high. As well as by increasing or decreasing the water consumption. Decreasing the water consumption results in the increase of temperature. Increasing - its drop. Depending on the season of the year, the temperature of water feeding the heater will change. Colder water in winter will require stronger heating which will require the setting of higher heating power. Efficiency of warm water depends on the temperature of inlet water.

6 Czyszczenie filtra wody In a situation when the filter is partially or fully blocked, follow the steps: 1. Disconnect the power supply 2. Unscrew the fastening screw located at the bottom of the casing (pict. 1), then take the casing off holding it in such a distance from the heater so that the belt cable connecting the keyboard with the heater was not stretched, and then disconnect the cable by taking out the plug from the socket marked KEYBOARD (pict. 2). 3. Close the control valve (marked 1) 4. Open the plug of the control valve (marked 2) 5. Take out mesh and magnetic filters (marked 3, 4) 6. Remove dirt 7. Insert filters 8. Close the valve plug. 9. Open the flow on the control valve and check the watertightness of connections. 10. Connect the belt cable to the keyboard plate (pict. 2). 11. Close the casing 12.
